@iti-tch tatc @strut @fitta Iurnovro WINDOW sass 'rasrtrra r SPECIFICATION. 'rc Ala WIIOM Ir MAY coNcEnNo no a known ann 1,2. B. wnnnnnn, of Rookford, intro oonnny of winnobngo, nndsnnto ofjIiunoio, novo o invented anew and Imprved Sash Supporter andI do hereby declare that the following is a full,clear, `and,

exact description thereof, which will enable others skilled. in the art to make and use the same, reference` being had to the accompanying drawings, forming a part of this specification. p This invention relates to an improved sash supporter by which simplicity, durability, ,and cheapncss together with convenience and facility of operation arersecured, and it consists in an adjustable,.selfoperating eccentric roller, composed of india rubber, gutta percha, or--any of their respective elastic or liexible compounds,`

-or of any other suitable elastic or iiexible material, which roller is so hung or attached` to the stile of a window sash, that when theroller hangs on its bearingsand the sash is being raised, the roller will `notobstructt-,hc` I same in the least, but the instant `the hand is removed from the sash it will be so operatedor turncdas to firmly bind against the side of the window frame, and thus `securely hold the sash at the heightor point towliich it was raised, whether more or' less, while at the same time, when so desired, by properly relieving the `roller from its bearing against the lwindow frame, the sash can be then lowered and closed at pleasure, as will be apparent from the following detail description of the supporter, and the mode of arranging the same upontho sash, reference being had to the `figure of the accompanying plate of drawings, in which the upper and lower sashes of a window frame, are shown with my improved sash supporter applied to both of thesame.

A inthe drawings isa round roller or wheelmade of wood, metal, or any other suitable material of an inch or more or less in diameter, and covered around its periphery or edge1 with rubber, gutta percha, or any of their respective elastic or iiexible compounds, or with lany other suitable ilexible or elastic material, in and through` the centre of this roller a small hole is made to receive a screw for securing a knob B to it. Anotherapcrture is also made in and through the roller, halt` way or nearly so from its centre to its outer edge or pcriphery,\wl1ich aperture, if the roller is made of Wood or entirely of rubber, should be suitably hushed with brass or other metal.

Through this eccentric aperture of the roller a screw is loosely passed screwing into the stille of the sash, the outer cud of its bushing being countersunk, so that the head of such screw can comeush or suiciently so with the outer face of the roller. -A metallic plate is then placed on the outer. face of the roller, andthe;

knob B then secured to it by screwing its screw, shaft, or spindle into the centre aperture ofthe roller.A If the roller A is made of porcelain, earthenware or metal, I deem it best to mould both it and its knob in one and the same piece, with a suitable aperture through it to receive the screw by which the rollerA is to be hung to the sash-stile, the' edge of the roller being then covered with rubber or its equivalent, as before explained. And, I

furthermore, if the roller is made of metal it might be desirable in some eases to. plate its outer face or surfaces aswell, also, as the knob, with silver or gold, and use the white rubber, so known, for a covering to its edge;`

this mode of manufacture vproducing a highly ornamental and beautiful finish to the same. VThe body of 'the roller may be also made of coiled wire with the ends of the wire en each side turned in, in the form of aneyc `to receive the screw for fastening it to the sash stile-, and then an ornamented knob secured to Lthe proper `side i of it, and the periphery of the coil covered with rubber. C If the rollers are made of soled rubber it would ,be` best to make the end of the knob .which bears against it, sufficiently large to cover the screw-head, by which the` 1 roller is fastened to the sash, thus dispensing with the metallic coveringplate thcrefcni` `In applying the eccentric roller, A, to the upper sash, I mortise or cut a cavity, C, in the back of its stile, in which cavity I then place and secure the rollers by means of a screw passing through its eccentric aperture, with` the rubber edge or I periphery against the window frame; to the roller, I then han g a bent leverharm, D, having aknob, F,`,`at 'its outer end in such a manner, that by rasing it the' roller can be relievedV from -the window frame, thus leaving" o the sash free to fall when removingl the hand from the said knob, the eccentric roller then com-es to a close or firm bearing against the window frame securely holding the sash in such position, whether at agreatcr or less height, as is obvious by an inspection of the drawings withoutany further explanation.

It is not necessary to touch the lever-arm, D, when the sash is being raised, as the roller then offers no` obstruction to the passage or sliding of the same. 'Ihe knob atrthe end of the lever-arm D may be made of any:

desired style or shape, and in order to prevent injury to the said lever, I attach to the sash-stile, a long `staple or guide, Gr, under which the lever` plays or moves, and by the sideof Vthis guide I also insert a small holt or` 1 rest-pin, K, for the lever, the object of this arrangement being two-fold, viz: first, to allow suiicient movement or play to the lever-arm to properly operate the eccentric roller; and second, to preventany possible injury to or displacement of the roller or the bending of the lever. Inapplying the eccentric roller to the lower sash the' Lever-arm is dispensed with, a knob being attached directly to it, and a. helieal'shaped spring, H, also used upon the window iframe for ruily holding the rollerto it when the sash is closed, in order to `prevent its being raised, thus operating as a fastening to the sash, between which spring and the windevY frame the roller is interlocked a suitable lshaped cavity or depression, I, being made in the said frame'to receive the edge of the roller, and thus render its fastening .by the said spring more reliable, as plainly seen byan inspection of the drawings.

Among the many advantages secured by my improved sashsupporter herein above described, may be here mentioned its simplicity, ease, andcovenience of operation; the sashes having itapplied to them moving asleasy as though they were notapplied, while at the same time the supporters are ever ready to act upon the window frame the instant the'hand is relieved from the sash, holding it iirm :at whatever height it may have beenxaisedV or lowered. l

I do not claim an eccentric roller-'as new in itself, but what I claim as new, andl desire to secure by Letters Patent, is.;- Y l l I claim thee-combimiti'onl of '-therollerileveifarrn hD, 4secured to.. it, iixedstaple or guide G, and stop or rest`- pin K, 'when arranged together asvv and forthe purpose described. l i The above speciiication'of my invention `signed by me this 23d day of January, 1866.
